To all whom. it may concern.-

Be it known that I, EDWARD 'H. ELDER, a

citizen of the United States, residing atNor.

wich, in the county of New London, State-of Connecticut, have invented certain new and useful Improvements inEjectors for Firearms, of which the following is a full, clear,

' ward end of the latter to a point substantially and exact description. I

This invention relates to that class of ejec-,

tors for firearms in which the act of break-- ing down the arm serves to set the shellejecting mechanism in operation to effect the starting of the shell from its'seat in the b ar-, rel either sufiiciently to permit it to be grasped and withdrawn or with such force as to cause it to entirely leave the arm.

The particular object of this inventionis to provide a device of the class mentioned which shall be of very .To assistin explaining my invention, I have provided the accompanyingsheet'of draw-' ings, illustrating the same, as follows:

Figure 1 shows, partly in elevation and partly in vertical central section, a portion 'of an arm fitted up with my newly-invented shell-ejecting device. Fig.2 is a view similar to Fig. 1, showing the said arm brokendown and serving to explain the manner in which my newly-invented shell-ejecting mechanism operates. Fig. 3 is a rear end ele-.-

vation of the barrel'of the arm. Fig. 4 is a cross-sectional View of the said barrel, taken' tached from the-arm and serves to illustrate a modification of my invention.

Referring to the drawings, the letter a denotes the frameof the arm, and 'b the-barrel, the said frame and barrel being hingedtogether by the joint-pin c, which latter is fixed in the frame aand passes through the barrellug d, near the forwardend of said lug, in

substantially the usual manner. v

The letter e denotes the-ejector-bolt, said bolt being located in a chamber b, beneath and parallel with the-bore of the barrel 1), and capable of limited longitudinal movement within the said chamber. The ejector-bolt e bears a head e, which when the bolt is in its simple construction and may be cheaply produced.

Fig. 5 shows in elevation certain ele-- Y inner or forwardposition forms a part of the rear end of the barrel-and is formed with a iii-which the flange of theshell is recess 12 received.

lug d'midway its width and extending parallel with the length of said lug from the formidway its length, and at -or near its forward and rear ends the said slot opens into the ejec-,

front or shorter arm extending into the chainberv b in such manner that a spring k may be confined between the said lever e adjacent end of the ejector-belt lever ghas a longer arm extending rearwardly 'The letter d denotes a slot located in the- 'Thepin'f serves as the pivotal support ofa lever g, located injthe slot d and having its;

atsubsta'n-tially right angles to the said shorter arm,the end of which sa'id'longe'r arm is turned r upward and is adapted toenter the chamber 11',

so as .to engage anotch e in the ejector bolt e. The ends of the lever g enter the chamber b through the openings at the forward and rear ends of the slot d, serving to connect the said slot and chamber. Near the pivotal support fof the lever g the lon'ger (rearwardly-extending) arm of the said lever passes through a notch cin thehinge-pin c', the bottom wall of which notch is'adjacentthe. confronting edge of the said longer arm of the lever-g.

When the arm is closed, as shown in Fig.

1, and the ejector-bolt e is in its forward po-,

sition, the spring h, confined between-the said bolt and the shorter-arm of thelever g, serves to retain the 'saidlever'in such position that the end of its longer arm enga es the notch e of the ejector-bolt. Upon breaking down the arm the act of rocking the barrel upon thejoint-pin 0 moves the longer a m of. the lever g upwarduntilthe edge of'the said longer arm is carried into'co'ntact with the bottom Wall of the joint-pin notch 0'. Gon

tinued rocking-of the barrel upon the jointpin 0 then results in causing the lever 'g to swing upon its pivotal supporting-pin f until the end of the longer armis withdrawn from V the ejected-bolt notch 6 limited by operate satisfactorily in the manne tion.

The lever 9 leaves the ejector-bolt notch 0 slightly in advance or simultaneously with the completion of the breaking down of the arm, and upon such releasing of the ejectorbolt e'the spring It acts at once by expansion to shoot the said bolt rearward, and, assumingashell kto have beenin place in the barrel I), such action of the said bolt carries the shell from its seat in the barrel, the bolt-head e engaging the flange of the shell in the usual manner and as before explained.

The rearward travel of the ejector-bolt e is its engagement with the head-. block a of the frame a, and upon the closing of the arm the bolt-head e rides downward upon the face of the said headblock, causing the ejector-bolt e to move forward into its chamber 1) and causing also the compression of the spring h betweenthe bolt end and the shorter armof the lever g. The spring h when under compression rocks the lever g, so as to hold the end of the longer arm of the lever in engagement with the ejector-bolt e, and the said bolt in its forward travel rides upon the said lever end until the latter is coincident with and enters the notch c of the ejector-bolt, which action occurs upon the return of the bolt to its normal or starting posi- While the spring h is found in practice to described to accomplish the ends for w ich it is provided, in addition to the said spring means may also be provided (shown in Fig. 5) for positively starting the ejector-bolt from its seat upon the breaking down of the arm, thus overcoming any possible tendency the bolt might have to stick in its seat in the chamber 1).

. Continued rocking of the lever then serves,

Referring now to Fig. 5, the letter e denotes a shouldered-down extension of the ejectorbolt 8, the forward end of which extension is adjacent the shorter arm of the lever g, and upon said extension the spring h is mounted. When the lever g is rocked upon its pivtal support f in the act of breaking down the arm, the shorter arm of the lever is rocked into engagement with the adjacentendof the shouldered-down bolt extension e simultaneously with the withdrawal of the end of the longer arm of the lever from the ejectonbolt notch 8 as shown in dotted lines in Fig. 5,

through its enga ement with the said ejectorbolt extension e to start the said' bolt rearward positively, after which the spring it acts in the manner already described to complete the rearward travel of the said bolt to discharge the shell;

Having now described my invention, I claim- 1. In a breakdown gun, in combination, a notched ejector-bolt mounted to slide in the barrel-lug, a bell-crank'lever pivotaJly mounted in said lug and having one of its arms extending rearwa'rdly with its end bent upwardly to engage in said notch of the ejectorbolt, a member fixed with relation to the le ver and disposed rearward of the pivotal point of the latter in position to contact with said rearwardly-extending arm and force its engaging end out of the notch of the ejector-bolt when the barrel is swung open, and a spring arranged between the other arm of said lever and the adjacent end of the ejector-bolt, substantially as described.

2. In a breakdown gun, the combination with a notched ejector-bolt mounted to slide in the barrel-lug, and the joint-pin, of a level intermediately pivoted in said lug forward of the joint-pin and having an arm extending rearwardly beneath the pin with its rear end bent upwardly to engage in said notch of the ejector-bolt, said arm of the lever adapted to contact with said pin when the barrel is swung open and effect the withdrawal of its engaging end from the notch of the ejector-bolt, and a spring arranged between the other arm of the lever and the adjacent end of the ejectorbolt, substantially as described.

3. In a breakdown gun, the combination with a notched ejector-bolt mounted to slide in the barrel-lug, and the joint-pin notched transversely in its under side, of a lever intermediately pivoted in said lug forward of the joint-pin, and having an arm extending rearwardly'beneath and positioned in said to engage in said notch of the ejector-bolt, said arm of the lever adapted to be moved to withdraw'its engaging end from the notch of the ejector-bolt by contact with the joint-pin when the bari-cl is swung open, and a spring arranged between the other armor said'lever and the adjacent end of the ejector-bolt, substantially as described.
